mechanism,- so that the: stationary members or constituent parts thereof fit snugly therein while the recesses or-cavities thus prodnced for the reception of the movable mem- 15 bersthereof afford a smallest posible clearance only in order that a largest possible cross-sectional area may be maintained at the fore-end-of the stockfor the purpose of withstanding external stresses to which fire-. arms of the stated kind are subjected in handling AS: a result thereofthe inner parts of the lock mechanism are not readily accessible and in order to gain access thereto it is necessary. to .remove thestoek from the firearm which is very inconvenient and troublesome.

Especially in case of sporting guns and rifles which require a butt-end of neat. andgraceful configuration, the space available for the accommodation of the lock mechanism is inadequately confined due to the given, or desirable maximum cross-section of the foreend of the stock, but although the wooden body of. the stock is highly preserved in this way, still the carved or recessed end thereof is excessively weakenedso as to give rise to damage and breakage. The chief object of'my invention is to remedy this defeet.

With this end in view my invention consists in providing between the breech and the fore-end of the wooden stock a chamber for the reception of the lock mechanism, said chamber being confined by a top plate and by a bottom plate, both plates bridging the interstice between bridge and stock and rigidly connecting them, while the said chamber is laterally closed by two detachable parts. The said'bottom and top plates or bars are larger and of greater thickness chamber may be so drmensioned that when detached the frontal essential parts of the.

lock mechanismonly will be. visible. and

readily :aecessible. or, alternatively, they, may be of a, size to extend sutfieiently far-.towards. the. rear toexpese when removed. alli underlying parts of; the .lock mechanism inelusive.- of; the safety device, the transpos 1ng= device and; the, -trigger mechanism.

For the purpose ofliner'easingthe rigidity and firmness. of the structure and reducing at the same. timethe sizeor areaof the detachable laterali walls,-v particularly as regards the vertical: width thereof, I prefer to shape either the-topbaror the bottom bar or bothso as to somewhatproject with their free edges towards. the centre of the side openingsinto which. the detachable lateral walls are-to be inserted; but without inn pairing the accessibility of thelock mechanism in the chamber. It will be understood that in this way the. inter-connection accomplished between the breech or ba rels and the stock; of: thearm by means o the said plates; will beconsiderahly reinfnrped while at the same timethe size of the lateral openings.- of thechamber can he. so much. re duced therebythat. plain. pieces of; sheet metal: orthelike may be used for! closingthe said' openings. The. means required. or preferred for locking the closing pieces, members or walls-in their. closing positions may be of any conventional type such as small levers, sliding studs or the like adapled to be manually operated without the necessity of employing 'any tools 15 will now proceed to describe-my invention more in detail in connection with. the several embodiments thereof, illustrated somewhat diagrammatically on the accompanying drawings, it being understood that the invention is limited to the embodiments thereof as illustrated and described.

When the stock of the gun is shaped like the butt-end 'of; a2 pistol-a bore 7 is tobe provided therein for the reception-of the bottom bar.- 14 as shown in- :Figures' 1, 4 3411117. yf d' .i. I i

In the modification'illustrated-in Figures 4 to 6 an undivided coherent shell as made of steel or any other: appropriate metal is 'substituted for-the combinedzshelli composed of a wooden part andia metallic part as shown in Figure 2. In some cases =I-'prefer-,"hojwever, to cover the outer faceof :the, metallic shell .9 .with a suitable veneer. This amodi- Jan fication involves a considerable enlargement of the chamber for the accommodation of the lock mechanism so that the constituent members of the latter can be given a higher degree of resistance against wear and breakage by increasingcertain dimensions there- 0 c V p urthermore in the embodiment shown in Figures 4 to 6 the lateral clamping projections or noses- 3 and 4 of the top bar 13 and the bottom bar 14 respectively are elongated to form semicircular rings or segments 1' cooperating to enclose and cover the jointat the fcre end of the-woodenstock,

indicated by the dash-and-dot line A-B and to ensure the-interconnection of the two shells and the stock. I

*In the embodiment shown in-Figure 7 the top bar 13 and the bottom bar 14 are enlarged in width and shaped to form lateral flanges inthe'ma'nner of a vaulted structure adapte to 'partiallyencloseand laterally cover the chamber ion the accommodation of the lock mechanismas; clearly shown with relation to the top bar 13in; Figure 7-. "In this way the rigidity and strength of the connection be-' tweenthebreech and the stock are consider ably.- inc eases-ma a't the' same time the sur face area o'f-the I shells e' can becOrre'spondinglyreduced'iso that the latter can more con- Veniently 'bemadeof metalonly in the shape of airundivided coherent plate.

Asshownin Figure 7 the covering shells dr plat'es s are -pivotally connected with the bottom bar 'l4"so that the chamber can be opened for access to the ldck mechanism by turning the'plates 8 about their pivots-15'.

What I- claim-gisz 1 1. In a firearm of the characterreferred to the combination of a breech structure, a wooden stock whereof the fore-end terminates a distance'remote from and behind the body of the breech to form a chamber for the accommodation of the lock =me-chanism therebetween top and bottom barsin firm connection with the said breech structure and stock, the two bars constituting the top wall and the bottom wall respectively of the said chamber and two detachable plates or shells constituting the side walls of the said chamber.

I 2. In a firearm of the character referred to the combination of a breech structure, a wooden stock whereof the fore-end terminates a distance remote from and behind the body of the breech to form a chamber for the accommodation of the lock mechanism there between top andbottom bars in firm connection with the said breechstructure and stock at least one of said bars being vaulted so as to partly cover said lock. chamber and reduce the area of its free lateral opening and'two detachable plates or shells constituting the side walls of the said chamber.

3. A lateral cover for the lock chamber of the firearm of claim 1 consisting partly of wood and partly of metal, the cover provided with interconnecting means for detachable connection with the arm and the Wooden portion thereof forming a continuation of the Wooden stock.

In testimony whereof, I eflix my signature.
